The extra power also means improved performance. The BMW M3 Sedan and BMW M4 Coupe with optional 7-speed M Double Clutch transmission sprint from rest to 100 km/h (62 mph) in just 4.0 seconds (without Competition Package: 4.1 s), while the BMW M4 Convertible reaches the same speed in 4.3 seconds (without Competition Package: 4.4 s). The sprint time for models with the standard 6-speed manual transmission is likewise 0.1 seconds faster in all cases than without the package.

The Competition Package also includes Adaptive M Suspension, which has been extensively tuned to the enhanced performance and handling, and which features new springs, dampers and anti-roll bars, along with reconfigured driving modes (Comfort, Sport and Sport+). The standard Active M Differential on the rear axle and DSC Dynamic Stability Control have likewise been configured to match the upgraded dynamics. Exclusive forged, machine-polished, weight- and rigidity-optimised 20-inch M alloy wheels – front 9J × 20; rear 10 J × 20 – with exclusive multi-spoke 666 M styling and mixed tyres (front: 265/30 R20, rear: 285/30 R20) complete the list of chassis upgrades.

For the BMW M3 and BMW M4 Coupe, the Competition Package includes special lightweight M sports seats that combine perfect support under extremely hard driving with exceptional comfort on long journeys. Seatbelts with woven-in BMW M stripes cap off an extremely sporty interior ambience.

Eye-catching exterior highlights of the Competition Package include the M sports exhaust system with black chrome tailpipes. Even more than its good looks, the most distinctive feature of the M sports exhaust system is its potent sound, which brings added emotional resonance to the driving experience. The starting rumble and the distinctive burble on overrun never fail to get under the skin of dedicated drivers time and again.

The Competition Package for the BMW M3 and BMW M4 is topped off by extended BMW Individual high-gloss Shadow Line exterior trim. The high-gloss Black finish has been applied not only to the side window trim, window recess finishers and exterior mirror frames and bases, but also to the BMW kidney grille, the side gills and the model badge on the tail.
